Abstract
|
|
|
|
Coconut haustorium (CH) is formed inside coconut shell during coconut germination. This study aimed to investigate the compositions and contents of CH phytochemicals. Phytochemical compositions and contents in CH were analyzed by ultra-high performance liquid chromatography?tandem mass spectrometry (UHPLC?MS/MS) and spectrophotometrical method. Five phenolic acids and four flavonoids were identified in CH. Ferulic acid and myricetin were the most abundant among phenolic acids and flavonoids identified in CH, respectively. Nepetariaside and 1-methylene-5α-androstan-3α-ol-17-one glucuronide were the most abundant terpenoids and steroid derivatives identified in CH, respectively. To our knowledge, this study screened several classes of phytochemicals in CH for the first. Terpenoids and steroid derivatives were likely to be more major phytochemicals than phenolic acids and flavonoids in CH. The functionality of CH itself and the compounds found in CH might be utilized in functional foods or cosmetics.
